Kernel panic - considering re-install.... questions

So my Kernel Panic on my dual G5 PowerMac is apparently pretty serious. I am able to boot up from my Tiger installation disc, and I'm able to repair permissions AND repair disc.... but doing those multiple times (and now being told everything is fine) doesn't stop the kernel panic from happening. It happens on boot-up almost immediately after the Apple logo appears.

I'm considering re-installing Tiger as my next option, but I've never done a re-install without wiping my hard drive first. Obviously I don't want to do that in this case because I have all my iTunes and my documents on this computer, among other things.
My question is, will I retain everything in my home folder if I do a re-install on this machine? Or will that stuff be inaccessible/wiped out?

I do realize that some stuff will be gone, like preferences that I've set up in many apps, etc... I'm just most worried about blowing away the tens of gigabytes of stuff in the home folder, mostly music, pictures and docs.

For future reference, you don't want to repair permissions from the Install disk. They should be repaired from the startup volume itself.

"When possible, disk permissions should be repaired while started up from a Mac OS X volume (hard disk) that contains updated Mac OS X software, instead of a Mac OS X installation disc. Mac OS X software updates may change permissions on some files to improve security. When this occurs, the version of Disk Utility on the Mac OS X volume is updated to account for the new permissions. Running Disk Utility while started from the Mac OS X volume ensures that the changes made by software updates are preserved."
